' Application filed February 4.1922.

To 053.? 'm/mm. it may concern Be it known that Rononr JoKsoH, mechanical engineer. citizen of the Republic of Czechoslovakia. residing at Prague-Karo- .linenthal. Czechoslovakia, have invented cer tain new and useful Improvements in Multiplying Machines of which the following is a specificatioin reference being bad therein to the accompanying drawing.

This invention refers to a multiplying machine whereby; by a setting of the multiplicator and the n'iultiplicand, the product of these factors appears in small travelling window in the apparatus. i

The multiplying machines are not suitable for use because. for instance, the salesman has to direct his whole attention to the handling ot' the machine for the. purpose of counting the rotations of the crank and the displacement of the slot of the multiplying machine in progression of tens and consequently finds it dillicult to attend to the customer without making mistakes. 1

hilultiplying machines with toothed gearing also operate much too slowly and they are not sutliciently reliable for use in a. retail. business. as the figure discs under the effect of inertia due to their rapid rotation, oft-en rotate too far and therefore result in an in correct position.

In accordance with the present invention the defects above mentioned are done away with and the improved multiplying machine is therefore made particularly suitable for a retail business. It is possible to directly connect the multiplying device with the or dinary recording boxes or also with scales n which the weight is set by a system of levers. It is in this possibility that the advantages of the present invention particularly lie. as it is only necessary to bring in the tun t'lamental price by a simple rotation of the crank or by actuating any working device of the multiplicator. The final amount is then automatically obtained by hitherto known in a retall shop,

the setting in or determination of the weight by means of the setting levers of the scales. The series of operatlons of the different levers of the scales or recording box for ob taining the correct final amount by the multiplying device is then equivalent.

"The essentialfeatures of the improved multiplying machine are in the first place a tabulation displaced in series of tens in seping.

Running over eachpair of rollers 2, 2. which may be rotated in unison by means. of engaging toothed wheels, is a band 5 furnished with tabulations. These tabulations'consist of columns of figures showing the final 'prbdfor instance, by setting the crank 3 for the price 2 upon the first band 5, are shown con secutively the figures 0, 2, 1, 106, 198 in the direction of the axis of the roller 2; on tlfe following hand 5, the n'iunbers 200, 202 396, 398; on the third band 5, the nuinhers 4:00, 102 596, 198 and so on; on the last band (tenth) 1800, 1802 1998.

For the price 3, set by a very slight rotation of the roller 2, there are shown upon the bands 5 passing over the upper rollers, columns of figures 0, 3, 0, 294;, 207 and so on. Thus the bands appear with the column figures showing the final productsttinal amounts) parts arranged side by side of a common tabulation containing all the final amounts, which tabulation, in its original form, could not be practically applied as a connected total.

In order that thedevice may be applied in a small way and therefore be adapted for practical purposes, the tabulation, as pre viously stated, is subdivided into small tabulation bands in tens which are so wound up above each of the two rollers 2 and 9 that by setting the price, corresponding columns also appear on the other rollers 9. on the indicator. The indicator forms a tabulation corresponding to the price which is formed by the upper columns of the separate tabular bands.

In the arrangement with two bands 2 there are provided at the sides of the machine and in a higher position than the guide rollers, two pairs 0t guide rollers 6 and. 6 arranged in angular relation to each other and upon which run strips, each provided with a'slit 7 and 7 respectively, which slits constitute a travelling window 8 at their crossing point. The guide rollers 6 and 6 are displaced by means of hand levers 9. 10 and 10. On the handle of the lever used to put in position, for instance, the hundreds, the tens and the units, is arranged an indicating finger 11 and such indicating finger can be moved over the correspondingscale 12. The two handles 10 and 1W each carry, as shown in Fig. 7. a clutch 13 and 13 which may be brought back to the normal position out of engagement with the chains 14C. By actuating one of the two handles the clutch 13 or 13 corresponding to said handle is brought into engagement with its chain 14, which serves as the actuating element for adjustment of the slit 7. The actuating means comprise toothed. wheels that give diff.- ferent transmission, two different speed arrangements ("tor tens and units) being provided. V The slit '7 has as many as different positions which, however, owing to the method of" driving in 9 positions tor tens and in 9 positions for units are reduced to gether 11018 positions. The chain 14: passes over two chain wheels 15 and effects the retation of the guide rollers. through a toothed.

wheel 16, (Fig. 7) loosely mounted on the shaft 13 and which is rigidly connected with the chain wheel The wheel (16) engages, by means of a pair of toothed wheels which are not vis ble, a toothed wheel also freely mounted on the guide rollers 18. In this manner the guide rollers (5 can be coupled with the handle of the levers 10, 10. The hand levers 10 and 1.0 effect the displacement of the slit '7 from top to bottom or vice versa, whilst the handle 9 effects the dis placement of the other slit 7 in the direction from left to right or vice versa, for which purpose. as shown in Fig. 5, the chain wheel 15 is rigidly coi'inected with the shaft 18 and the bevel wheels 19 which convey the motion. by means of bevel wheels 20, to the guide rollers (3 which. are located at right angles to the guide rollers 6. Through the operation of the hand lever 10, the slot 7 by the action of a corresponding toothed wheel gearing is moved ten times as quickly as with the hand lever 10, so that, in this manner. the setting of the tens can be effected just.- as quickly as that of the units.

Fig. 8 shows the guide rollers 2 with the tabulating band and a variable tensioning device 21 of the well known kind. Locking discs 22 are fitted to retain the guide rollers in position. .Mounted on a strip 2%.: are rollers 23 which engage elastically in. the locking discs 22. The intermediate wheel 2? connected with the crank 3 engages with the driving gear 20 on the spindles ot the guide rollers.

of the rollers. which are arranged in two groups, the upper rollers 2. are used "for reading off the figures. and hence are provided with the locking device 22 and. 23 which retains the rollers in such position that each column of figures comes over the most highly situated surface of the rollers. The lower rollers 72 serve to carr the tabu lating bands. and are provided with the above mentioned variable tensioning devices 21 so as to n'iaintain the hands in tension.

Fig. 9 shows by way of example an arrangement of the device with 3 bands. 9?. 28, Q9, of which the upper one 29 indicated in the drawing as a plate. The band 27 is passed over two rollers 29 2-30. so that when the two rollers are rotated, in similar manner, the band born the one roller is unwound and wound on the other. The two rollers 29. 30, are rigidly coupled together by means of two pairs of bevel wheels. 31 and 31 one wheel of each which pair is fixed on. a shaft 32 adapted to be actuated by a hand lever 35, by means of a hollow shaft 34 mounted on the shaft of the lever and a couple of llOOiTllQtl wheels 33. The third band 28 is an endless band passed over tour rollers 36, 37, 38, 39, one of which, namely 36. is the driving roller. This is mounted conjointly with a toothed wheel 4.0 on the shaft 32, and is driven by the roller the section of the product column betoothed wheels 40, ll, and, the hollow shaft- 42, by a hand lever 4-3. Thelever 414 actuates a shaft 45 to which is keyed a toothed wheel 4:6 that gears intoa toothed wheel 4-7 freely mounted on the shaft 252, andv which carries a crankpin 457" and actuatcs a crank disc 49 through a linlr ltl. This transmits the rotation, by means of a shaft 50 to a toothed sector 51 which operates a raclr bar 52 and in this manner displaces the plate 29. For the sake of clearness the plate 29 is shown in the drawing as formed with only 5 slots ('31, 62, 63, 64-, 65, instead of l0. The bands 27, 28, each have a slot, 59,

respectively. The guide rollers and wind- .ing rollers on which the tabulating; bands 27, 28, are mounted are constructed 1n the same manner as shown in Figs. 1, 2, 3and 8.

They are driven conjoifntly by means of. a shaft 53, which carries a chain wheel 54 over which runs a chain The chain is kept in tension by means of a chain wheel 56 freely mounted on the shaft 32 and is brought in connection with a slide 57, which sets the price by means of a pointer 58 working over a scale, which is not shown, where l l the price may read off.

The operation, when it is desired to effect multiplying operations, and the manner of working the bands, are as follows By setting the pointer 58 to the figure which indicates the price onthe scale associated therewith, the guide rollers or winding rollers of the tabulation are caused to rotate, and these are wound or unwound so that all products of the multiplier (fundamental price) within the scope of the multiplication appear on the upper side of the guide rollers in such a manner that along the upper surface of the roller cylinders,the products of a number are always shown (in the present constructional example from O to 9) of the highest place value of themul tiplicand, in the first constructional example with two bands. Let us say, for example, that the number 832 is to be multiplied by 573. The indicator sets 832 on the scale, when there appear on the first guide roller all products of 832 0 up to 832 9 9, on the second guide roller all products of 832x100 to 832x199, etc. In the present construe tional example, the last, that is to say, the tenth guide roller shows all products from 832X900 to 832 999. Now, if the slot 59,

-whieh here corresponds to the hundreds,

that is to say, the third position value, of the multiplicand, is brought into position 5, it leaves the product column of the fifth guide roller free, that is to say, all products from 832 500 to 832 599. If then the slot 60, which in the present example corresponds to the tens, that is to say, the second place val. ue, is brought into position 7 it leaves free out of the product column of the fifth guide tween the product from 832x570 up to 832X 9. This arrangement of the product column yields a strictly graduated order in tenths of the products, lines appear in lines, and the products of the hundreds in columns. Any other desired arrangement of he product may, however, be employed. In the constructional example under notice, this arrangement of the prod.- ucts was selected with reference to this example and for the sake of greater clcarness. In accordance with the example of' calculation shown above, it is only necessary that the so-called unit slots, 61, 62, 63, 6-1, (35 of theupper plate 29 should be brought into position 3, for the product of 832 573 to be read off throng-lithe travelling; window, namely 476736. The unit slots are constructed in such a manner that their part, (i) Fig. 10, on plate 29'is width of a tenths slot of one band, and their width (m) is a tenth of the width. of a tenth slot. By this means, of all the tens spaces which the tenths slot may leave free, only the space ofa unit slot is left open,

which corresponds to the actual figure ot' its position value, and of this again the hundredths slot situated underneath leaves only a portion open which corresponds to the multiplicand which has been set, while in consequence of the setting of the multiplier (fundamental price) the 'iroduct of the two factors appears through the open ing. u

By increasing the number of the guide rollers and that of the guide bandsor slots,

the scope of the multiplication may be enlarged to any extent. With reference'to Fig. 11, let it be assumed that 2, shall be multiplied by 573. The operation is then as follows Through the rotation of the crank 3 the figure 2 is brought to appear in the window 58. By this rotation of the crank, the rollers 2 and 2 (the roller 2 is not Visible in Fig. 11); are so rotated that the columns of figures on the 10 rollers will appear at the top of these rollers. Thus, on the first roller tube, atthe left hand side of Fig 11, there will appear the column with the products from 2X0 to 2X99. column there will appear the column from 2 1OO to 2X199, on thethird column the products from 2 200 to 2 299, on the fourth column the products from 2 300 to 2X899, on the fifth column the products from 2x400 to 2x499, on the sixth column the products from 2 5OO to 2x599, and so forth see also the tabulation shown on Fig. 12). All these columns of figures are hrought'to one level. and correspond to the figure 2 appearing through the window 58. 2

Now, the multiplicand 573 is formed by On the second and coluinns, so that all productsof the units and tens setting the hand lever 35 for the hundreds into the position 500, the hand lever 43 for the tenths into the position. 70 and the hand lever 13 for the units into the position 3. By adjusting the hand lever 35 to the posi tion 500, the rollers of the band 27 will rotate to such an extent that the slot will regiser with the sixth roller 2 counting from the left in Fig. 11, so that only the column of figures on the sixth roller will appear in the slot 59, whereas the figure columns on all the other rollers remain concealed.

lVhen the hand lever 4:3 is adjusted to the position 70, the band 28 with its slot (30 is brought to a position in which, if the bands 27 and 29 were missing, there would be visible on the first roller 2 only the products 2X70 to 2X79, on the second roller the products from 2 1TO to 2X17), on the third roller the products from 2 270 to 2 2i9, etc. As the principal band however, covers all the rollers except the sixth roller on which roller through the band 28 are covered all the figures except those from 2) to 2x579, there need only be adjusted new-x the hand lever 43 to the position 6 whereby the plate 29 is correspondingly IHOYQfl. This plate contains 10 slots 61, 62, (53, ('34, G5, 66, 67, G8, G9, 70, of which nine slots are always covered by the band 28, and of which in the present instance the slot remains uncovered. For the sake of clearness, plate 29 is shown broken off in Fig. 11 leaving the slot 61 to 65 out. hen the hand lever 43 is adjusted to the position 3, the plate 29 is moved to such an extent that its ten slots will register with the products in which the multiplicand includes the figure 3 in the unit position, while all the other products are concealed by the plate 29.

To sum up once more, in the example referred to, the slot 59 of the band 27 reveals the column with the figures 1000 to 1198. Of this column, only the figures llO to 1158 are revealed by the slot 60, and this part of the column is again covered up by the plate 29, so that through the slot (38 there appears only the figure 1146. Of the rollers and tabulations, therefore, everything is concealed by the bands referred to except the small portion becoming visible at the intersecting point of the slots 59, 60 and 68, and the figure 11% in the present instance is the desired product of the figure 2 multiplied by 57 3.

What I claim is:

1. A multiplying machine comprising casing, rollers journalled therein and arranged in pairs, means for rotating said rollers, a band carried by each pair of rollers and provided with columns of figures, the figure columns of all the bands showing the entire product of any desired range of multiplication and being divided i .o tenths, movable strips located above said rollers and having each one or more slots, means for moving said strips, the slots in the said strips at their intersecting point being adapted to constitute a travelling window, an indicator for setting the multiplier, and indicators for setting the multiplicands, the arrangement being such that by the setting of the multiplicand the final product of the multiplication is visibly displayed in the travelling window formed by the slots in the said strips.
